Proto Punch Center 7/16" J417/16-SBD

Proto's professional-grade 7/16-inch center punch designed for precise layout work and industrial metal fabrication. This heavy-duty tool is engineered to create distinct indentations that serve as accurate starting points for drill bits, preventing bit wander and ensuring exact hole placement. Manufactured from high-strength alloy steel and subjected to a specialized heat-treatment process, the punch maintains its point sharpness and structural integrity even under repeated heavy impact. Its black oxide finish provides excellent corrosion resistance, while the polished identification panel ensures the tool size remains permanently visible in busy shop environments. The shipping weight for this model is approximately 0.22 lbs.
